Re: [Bitcoin-development] New BIP: protocol for multisignature payments
Both wallet and server side implementations will be based on existing
code in me-friendly language (C++>Python>anything else). I don't have
a time for it right now but Crypto hackathon in Parallel Polis
(http://cryptohack.org/) seems like good opportunity for it. I will
let you know then.

Re: [Bitcoin-development] New BIP: protocol for multisignature payments
If you decide to implement this in an existing or new bitcoinj based
wallet, then I'm happy to give you pointers on how to do it. Making
one-off, cross platform app specific wallets is pretty easy these days. For
2-of-3 dispute mediation transactions they'd start out being kind of
specialist so asking people to move money from their general spending
wallet into dispute mediation app isn't unthinkable. Eventually general
purpose wallets would integrate protocol, UI ideas and maybe code.
At least, that's how I'd do it.

I didn't consider that, thank you for feedback! I will try to find

For one, it can show up issues in the design you didn't think of. For another, implementation is a lot more work than speccing out a few protocol buffers and high level procedures, so people who are going to write an implementation probably won't follow your design unless they have a great degree of confidence in it and some compelling reason to use it (e.g. interop with other users). -- Dive into the World of Parallel Programming.

Re: [Bitcoin-development] New BIP: protocol for multisignature payments
I know about that wiki page. I just wanted to design protocol which would make it easier in practice. (now it would be done manually) I could look at implementing it someday, but now I'd like to receive feedback from community. 2015-01-31 19:19 GMT+02:00 Mike Hearn : > Hi Martin, > > You're on the right lines.

Re: [Bitcoin-development] New BIP: protocol for multisignature payments
Hi Martin, You're on the right lines. Your writeup is pretty similar to the high level overview given here though: https://en.bitcoin.it/wiki/Contracts#Example_2:_Escrow_and_dispute_mediation To make 2-of-3 dispute mediation works requires implementing a wallet that supports it, and the tools mediators need to manage incoming tickets, etc. The BIP70 extension is probably the smallest part of the project.

Re: [Bitcoin-development] New BIP: protocol for multisignature payments
Ooh, I had a very similar proposal, except it involved sharing generic P2SH scripts. It also involved facilitating requesting of signatures..

[Bitcoin-development] New BIP: protocol for multisignature payments
Hello, I've been thinking about how to solve security problems of the servers holding huge amounts of bitcoins (exchanges, markets...) and came up with this idea: https://gist.github.com/Kixunil/2ec79cf40a53fb899ac5 TL;DR: it's extension of BIP70 (but not fully compatible due to security reasons) which supports making of multisig transactions dynamically. (The most important thing is that the user provides his address.) What do you think? Is it a good way to solve the problem or do you know about something better? I would really like this or something similar implemented by wallets. Thank you for your feedback!
